don't do anything to your car unless you want to boost. Everything else is pretty much just a waste of money because to get anything you'll be:

A) paying more than you would for boost
B) be getting less for that money

theres not enough in basic bolt-ons to warrant some of their high prices, esp. when the hit to the resale value is factored in.

with all the stuff primetime mentioned you'll be looking at maybe 10-15 horse at the crank, and on top of that you'll lose throttle response to the new CAI. and a throttle body is a hair brained idea as well.

i suggest you focus on getting suspension work done if you want the car to feel faster, it will give you the most noticeable gains in adrenaline, if thats what you're looking for.
